Custom Fiesta Modes

In the holiday fiesta playlist there were games like swat and sniper fiesta, where the different weapons you got were specific to the mode. Is there a way to customize super fiesta so you only get specific weapons? I’m thinking something like a mythic fiesta where you get random mythic weapons. Can anyone help?

Its been 3 days and no one had responded, even a no would be sufficient so i dont have to keep trying.

mods lemme know if im not allowed to do this
